Rasmussen, considered the "Gold Standard" Is using a breakdown of 37.0%D, 32.3%R.

This "poll" isn't even close to either standard.
I think Rasmussen may even be off with their numbers. The last party I.D. census I saw about 6 months back had Dems at 35%, GOP 32%. Maybe Rasmussen has more up to date numbers than I do, but the fact still remains NewsWeak is WAY off. Additionally, a national poll has very limited ability to project an outcome for Congressional elections, especially if this poll over-represents population centers in California, New York and Illinois.
